    Interface HeadStageAdapter

    The head-stage WRITERS the mirror wraps — the ADAPTER's, not the software mixer's.

    The adapter is the ONE seam every kind's head stage passes through: MixerEngine.applyHeadAmp composes the coarse gain encoder and the fine trim into a single dB and hands it here, for an input, a bus and MAIN alike. The software mixer beneath it holds a head stage only for INPUT strips (SoftwareMixerAdapter.setGain returns early on a bus, and the mixer has no strip runtime for MAIN at all), which is why wrapping the MIXER made MAIN's gain, trim and Ø unreachable while the row above them reported success (audit D18, task #46). MAIN is a strip: its head stage is the master lane's, and this is the seam that can see it.

    interface HeadStageAdapter {
        setAlign?(
            channel: ChannelId,
            delayMs: number,
            reference?: string,
        ): Promise<void>;
        setGain(channel: ChannelId, gain: GainLevel): Promise<void>;
        setPolarity?(channel: ChannelId, inverted: boolean): Promise<void>;
    }
    Index
    setAlign? setGain setPolarity?

    • OPTIONAL for the same reason as setPolarity — the mirror installs one when the adapter carries none, so an alignment reaches the lane on every console.

      Parameters

      • channel: ChannelId
      • delayMs: number
      • Optionalreference: string

      Returns Promise<void>

    • OPTIONAL on the adapter contract — the mirror installs one when the adapter carries none, so Ø reaches the lane on every console rather than only on adapters that declare it.

      Parameters

      Returns Promise<void>
